Thanks for the contribution and apologies for the delay reviewing!

>From what I can tell, the semantics match what we have already introduced for other Ops (e.g. `linalg.matmul` + `linalg.contract`). 

Since it's a Friday, I'm starting with the easier part - formatting 😅  I will go over C++ later.
